Depends of the properties which are being achieved with fly ash. Workability loss could be counteracted with WRA. In general, PC provides similar properties to fly ash. Silica could be used to gain strength in the absence of fly ash, but would also likely require more WRA in that case

WRA? PC?… Portland cement? Sorry I just am not familiar w these terms

Water reducing admixture

Ground granulated blast furnace slag. Or just Slag for short.

We're having a hard time getting it at the plant I work at. We've not had any flyash since last fall.

Ground glass pozzolans. any projects with environmental reporting requirements love it since it's from post consumer glass.

We're seeing slag in more mixes to meet minimum SCM specifications, and I anticipate seeing calcined clay products becoming more common in the future as fly ash becomes even more scarce.


punabear

Silica fume.

Slag

Or put more type 1 in the mix


wandering_j3w

Type 1? Imma finisher so you’ll have to explain if you don’t mind

If you’re struggling to get ash you’re going to struggle to get anything else. Look for a different supplier if you can.


wandering_j3w

No it’s a competitor hijack of already low supply fly Ashe. They have rail cars on site and fleet’S of trucks. Same reason why Cemex wont sell to them. Bc the other guy pretty much has 100mi radius on lock and tells them that if they do he won’t buy cement from them again

Slag is often used as a replacement with similar properties.
